In this study, climate change impact of future water temperature on the fishery resources was considered. Future water temperature changes of Kiso River and Ise Bay were calculated by coupled river-ocean model under the CMIP3 A1B scenario. Water temperature increase of Kiso River was about 3 degrees, and sea surface temperature increase of Ise Bay was about 2 degrees. Coastal areas were more strongly influenced.<br>By the analysis of observed data, the upstream migration timing of sweetfish was negatively correlated with water temperature difference (sea – river). Calculated future water temperature difference was smaller than that of present, which resulted in earlier start of the upstream migration of sweetfish.
